A conversational approach to spoken human-machine interaction, the primary and most stable mode of interaction for many people with cognitive impairments, can require proactive control of the interactive flow from the system side. While spoken technology has primarily focused on unimodal spoken interruptions to this end, we propose a multimodal embodied approach with a virtual agent, incorporating an increasingly salient superposition of gestural, facial and paraverbal cues, in order to more gracefully signal turn taking. We implemented and evaluated this in a pilot study with five people with cognitive impairments. We present initial statistical results and promising insights from qualitative analysis which indicate that the basic approach works.
